Rich Guyette is all about tree rings. As a founding member of the Missouri Tree Ring Laboratory, he and his colleagues use their expertise in reading, archiving, analyzing and storing tree rings to provide baseline data useful in a wide variety of fields. From fire histories to drought mapping, from carbon sequestration modeling to climate histories, the information found in these tree rings is wide-ranging.oldoak

One of their long term projects has been locating and analyzing ancient “sub-fossilized” oak trees embedded in the alluvial sediment along Northern Missouri rivers including the Missouri, the Grand and other Grand tributaries. With the information they’ve collected, they have created a database of midwestern climate going back 14,000 years.

Next time you’re climbing over piles of driftwood along the Missouri, keep in mind that some of these logs are ancient time capsules of climate and history.
